Hi, new to this group.
NanoVna ttrftech v. 0.5.4
NanoVnaSaver v. 0.3.7
I'm trying to use a home made fixture for testing chokes via S21 parameters, two short wires exiting VNA ports ending with clips
I've done a S.O.L.I.T. calibration with clips connected each other (thru).
Once calibration is applied and a sweep is done with fixture still in thru position (as per calibration) , software still shows the variable amount of reactance and a slight resistance variation across the sweep caused by the non-50ohm fixture.
Shouldn't I see a flat impedance 50+J0 ohm all along the frequency sweep instead, due to calibration correction factor ??
Am I perhaps wrong in calibration concept ??
Thank you
Federico
